To all whom. it may concern: j

Be it known that I, ORIN A. HANronD, a citizen of the United States of America, and a residentof Rochester, New York,.have 1nvented 'certain new and useful Improve,-

Glass-Blowing Machines, 'of which the -foli lowing is a speciiication. .v In an original application, Si'. No. 524,994,

Afiled Oct. 27, 1909 ofwhich this is a' di- *vision I have shown, described and' claimed f a glass-blowing machine in which, after a lglass thereon" has been placed in a., suita e .blow-pipe frame forming a part of the machine, and fthe action of the machine started, the blowpipe will be swung by power on a* horizontal Y, axis and be'positioned,verticallyl over the i .separable mold. and arrested in'that po` sition to permit elongation and molding, and wherein, after a proper interval, topermit the' elongation, the mold will be closed' by theupower.' In the type of the machine specifically claimed in, that-application, the application-of the power to the mold -closing mechanism is controlled by va timing elenient in the machine, which while autdmatic in its action is based upon the similar-behaviorof the successive gathers, whereas the period of elongation y required for each gather "varies with 'the condition of such gather, asto mass, temperature, etc. It is' obvious that these niay differ considerably in the several gathers under certain circum- Y stances and' I have therefore 'invented an automatic controller for the blowing and, molding, dependent not upon the pre-supposed condition of the gather but uponthe action4 of the particular gather being han- I led at vthe time, the controllervbeing actuated by the heat thereof after it has properly elongated. This I vbelieve to be broadly4 novel with mie. I will in this applicationpoint` out Oneway in which it may be ap- .plied to thc machine herein described.

The particular form of automatic control shown herein comprises `a thread preferably combustible Withsuitable means for posicoating a in the paal .of the' descending gather, the construction` being such that l will be applied to' close the in'olds. i ments .in Gather-Actuated Controllers-.for

-With the vmechanism above described is associated devices which are automatic in their action for replacing 'a fresh thread or posed as will be hereinafter described and.

. .f 6.5 the accompanyingdrawings claimed..

Referring to in which corresponding parts are designated by corresponding'inarks of reference :-Fig ure 1 is a side elevation ot a glass-blowing machine having' my invention applied thereto. Fig'. 2 is a front view lthereof with the blow-pipe in its vertical position. .F ig. 3 is a longitudinal section through the inachine shown in the above figures. Fig. 4 is a transverse section on line :c4-* of Fig.

Fig. 8 is a transverse vertical section taken on lines alg-w8 'of Fig. 5.. Fig. 9 is a transverse vertical section through-the fixed clip and Fig, 1Q 'is a longitudinal section on lines mll'fw'tiereof.

VThe blowing machine is of thel character fully described in my original application above nained,coniprising varame 1, in the top of which ismounted a blow-pipe frame 37,' to Vmove'iiiua. vvertical plane across the front of the machine, thenormal position of the frameA being substantially horizontal.`

Amotor 2v is mounted in. the .frame and through suitable clutch 15 is adapted too drive a cam disk 22,1iaving a cam run 88 by'A which the blow-pipe frame is moved from its normal position to a 4vertical position vsplit lng pi nier-3,525

or putting a coatl upon the gather, either ofwhicli might impair thenish.

'lt is obvious that the weight 153 merely affords a source of energy between the thread and the clutch. to actuate the latter with the consumption of-a comparatively small expenditure of power, and that it might onder circumstances be possible to throw the link `by vconnecting lthe cord 150 directly thereto.4 The construotion shown however is to be preferred, and as a i'neans of lifting the weight to store up the necessaryv energy l suspend it trom one end of a chain 154LL which, passing over a pulley mounted in the inain traine, has its op posite end connected to a horizontal arm of a bell crank lever '156, pivoted in the traine and having its vertical arm connected to the right hand end of a thrust bar 157, supported in the freine by a link 157, the left hand end of the' har being held against the periphery of the wheel by a spring 157b so'that on the rotation of the wheel the peripheral stud 158 will thrust the ber 157 eiidwise toward the right, depressing the horizontal end of the lever land lifting the weight, which is then caught by the latch'152 the thrust har releasing itself from the stud due to the continuedmoven nient of the letter and yfalling back to nornial position. rhe stud 158 1s so positioned on the *wheel that the weight is lifted soon after the initial engagement of the main ting from the top of the rear end of rod, 'Trrning two ears, between wl' read nasses from e spool 161 2 et 170 on a projection 171 tink. The lxed slip consists of a and coned lower end of a rod 17:2 which a collar'173A having a coned centraA recess, is adaptedto slide, the collar *,ieing normally pressed downwardly by e.

n2 l but being provided with av lin- 17H2 fr l. ilu closing bracket 91 'and with an ear 173c ed, when the collar is litted,`to be i itjnv r, latch 174 pivoted in iront the .tranne of the machine The collar is time `rearwardly, releasing :the collar 173, which `will he thrown down upon the coned surface the clip being formed by a. Y

tpted to be lifted thonnoid lifted hy the-closingr of the mold on one gathcnwhich positions it for theinsertion of the thread to control the blowing of the will strike and pass the collar forming part of the'iixed clip, the front end of the rod being depressed, after` which it will be restored to its normal level by the spring sup'- ported stud 175, thus inserting-the thread carried by the clip 1&6 between the ears of the fixed clip 1-1-5.y rEhe final rearward Inovev ment or' the rod will cause the rear end of 85v a har 17 G contained thereinto coact with an anvil 177 on bracket- 91 and will cause the lug forming the clip 146130 strike the lower end of the latch 174, throwing the llatch o of the clip 115, closing the latter upon-thethread.I The impact of thebar on the anvil will also shove the bar within the rod and cause the vconed end 176a upon the rear end of theformer to separate the ears of the movable .clip 146 so that as the rod 159 is drawn forwardly and separated from .the stationary clip, the ears ofthe movable clip will slip on the. thread and will not firmly engage it again until the front end of the rod strikes an anvil `177 onthe :projection 171, and is thus driven rearwardly again,

removing its coned rear end from within the rear end of the rod and permitting the 10E ears of the stationary clip to again-close upon and engage the thread. j

lne rod 159 is reciprocated by a pin and slot connection 178 with the pivote'd arm 147 connected by the driving spring 1438 with a y'driving 179 pivotedupon the saine center as the arm 1217 on the projection 171, the

adjustment of the partsbeing such that thev niofeznento the arm 179 to give afterwardv movement of the 4rod tends through the 115V spring to give. a vnaoiiement to the rod I after the 'movable clip has engaged the thread and th 1s both holds the thread taut vand placesth spring under tension. As the actuating cord 1:50 is attached to the piv. 120 oted Varrn 14:7, the burning of the thread permits the spring to jerk, the arm forwardly and thus release the weight as before described.'A

The driving arm 179y is swungupon its ,12,5

pivot to reciprocate the rod 15.9 for threading hv a drivingy device from the motor. In

the drawings thisconsists of a pin and slot 'connection 180 to the upper end off a, lever 181 pivoted in'theprejecton 171 on the' 130 @dri-ving mea-ns for closing'themoid and a tank,vthe lower end of the lever having a. pin and slot connection 182 with the downwardly projecting crank 183 onthe end of a shaft 184 carried inthe bearings 184 on the front of the water tank,the opposite projectingcrank 185 on the shaft 184' being connected by arearwardly extending link 186 with one arm of thebell crank lever 187,

the other arm of which is connected by a verticallink 188 with theb outer end 0f .'a.- lever 189 pivoted at 189?` on the frame of the. machine, the opposite end of such; lever ,bevin'g located adjacent to the face 'of the wheel 22. A setting lever 190 is 4pivoted at 190il to the frame 'of the machine above the pivot of the resetting lever and, has its end so located as to be struck by a pin 134 on the disk 22,

in the stationary clip. The inner end of'the j resetting lever will be raised at the same time into the path of the pin and then will be immediately engaged by the pin and bev depressed to permit the passage ofthe pin, this retracting the bar and resetting the .setting lever to be struck by the pin.

Inasmuch-as this divisional case has, in responsel to the requirement of the Patent Oliice, been filed to contain claims on the mold closing mechanism shown herein, failure to make claims herein which omit a recital of the mold closing means is not to be taken as an abandonment thereof, as such claims are reserved for my original application, Serial Number 524,994 before recited.
